Dab tsi yog yam uas cuam tshuam rau qhov ntom thiab qhov loj ntawm cov kab nrib pleb hauv cov chromium plating txheej nrog xoob qhov hauv hluav taws xob cua sov raj?

Dab tsi yog yam uas cuam tshuam rau qhov ntom thiab qhov loj ntawm cov kab nrib pleb hauv cov chromium plating txheej nrog xoob qhov hauv hluav taws xob cua sov raj?

Ntau qhov kev lag luam workpieces undergo anodizing (rov qab etching) tom qab tau plated nrog nyuaj chromium kom nthuav txheej txheej tawg, ua rau ntau qhov me me, uas yog hu ua xoob qhov chromium plating. Lub hom phiaj yog khaws cov roj lubricating ntawm qhov chaw txhawb nqa, txo kev sib txhuam coefficient, txhim kho hnav tsis kam, thiab ua kom ntev kev pab cuam lub neej. Nyob rau hauv cov txheej txheem sib txawv, chromium plating txheej nrog dot zoo li tus los yog zawj zoo li tus pores tuaj yeem tsim. Dab tsi yog qhov cuam tshuam rau qhov ntom thiab qhov loj ntawm cov kab nrib pleb hauv lub qhov xoob chromium txheej tshuaj xyuas los ntawm Changzhou nyuaj chromium plating hnub no?

Qhov ntom ntawm cov kab nrib pleb hauv lub qhov xoob chromium txheej yog nyob ntawm qhov kev sib tsoo thawj zaug ntawm cov tawv chromium txheej. Yog li ntawd, cov txheej txheem chromium plating muaj qhov cuam tshuam tseem ceeb ntawm qhov xoob chromium plating thiab yuav tsum tau tswj nruj me ntsis. Qhov nce ntawm qhov sib piv ntawm CrO3: SO42- hauv cov electrolyte ua rau txo qis ntawm qhov ntom ntom ntawm cov chromium plating txheej, tab sis qhov nce ntawm qhov dav thiab qhov tob ntawm lub mesh. Thaum qhov sib piv tseem tsis hloov pauv thiab qhov concentration ntawm CrO3 nce, qhov ntom ntawm cov kab nrib pleb kuj txo qis, thiab qhov dav thiab qhov tob ntawm cov mesh nce. Tsis tas li ntawd, qhov kub ntawm cov tshuaj plating muaj qhov cuam tshuam loj rau cov txheej txheem, vim tias qhov kub thiab txias ntawm cov mesh yuav thinner; Qhov cuam tshuam ntawm cathode tam sim no ntom yog me me.

Kev sib koom tes ntawm electroplating tej yam kev mob yog tus yuam sij rau kev tsim thiab tswj qhov loj ntawm chromium txheej cheeb tsam ntawm xoob pores. Cov xwm txheej rau kev tsim cov ntsiab lus zoo li tus thiab zawj zoo li lub qhov xoob chromium yog qhov yooj yim kho txawm tias cov txheej txheem plating ntawm xoob qhov chromium. Piv txwv li, qhov kub thiab txias thiab qhov sib piv sulfate ntawm cov tshuaj plating yog ob qho tseem ceeb hauv qhov xoob chromium plating, yog li kev sib koom tes yog tsim nyog.
